Hi, while using debian packages, we noticed that HeapDumpPath set in /etc/casandra/cassandra-env.sh or jv.options was not respected. This was due to the fact that debian init script was overriding it by calling /usr/sbin/cassandra with its own settings.
A jira have been opened with attached patch preventing init script from overriding this setting: https://issues.apache.org/jira/browse/CASSANDRA-13644 Please note that we may entirely remove also -H support in /usr/sbin/cassandra. This is handled in https://issues.apache.org/jira/browse/CASSANDRA-12849 Regards -- Close the World, Open the Net http://www.linux-wizard.net
